Global power generation company Cummins said it will launch the next engine in its “fuel agnostic” series, the X-10, in North America in 2026.
Part of the X engine family, the X-10 will replace the L9 and the X-12, with the versatility to serve both medium- and heavy-duty applications. The 10-liter displacement product slots into Cummins’ product portfolio complemented by the B6.7 and X15 and will serve vocational, transit, pickup and delivery and regional haul customers. Being introduced first in diesel, it will be compliant with U.S. EPA’s 2027 regulations a full year early.
“We are committed to advancing diesel technology while our markets and our customers need it to run their businesses. The new X10 has been designed drawing on our decades of experience as a leader in the medium- and heavy-duty space,” said José Samperio, executive director of North America On-Highway at Cummins. “We have applied those learnings to ensure the product will perform for our customers and the important jobs they need to do every time.”
The company said it expects the X10 play an important role serving customer needs for years to come. Though the engine will first be available in Europe and North America, it will be introduced in other regions over time and will be made for off-highway markets as well.
The engine is built on Cummins’ fuel agnostic platform. These new fuel-agnostic engine platforms feature a series of engine versions that are derived from a common base engine, which means they have some parts commonality. Below the head gasket of each engine will largely have similar components and above the head gasket will have different components for different fuel types. Each engine version will operate using a different, single fuel.
